AWS SDK for JavaScript in the browser and Node.js

AWS SDK for JavaScript

The official AWS SDK for JavaScript, available for browsers and mobile devices, or Node.js backends

For release notes, see the CHANGELOG. Prior to v2.4.8, release notes can be found at https://aws.amazon.com/releasenotes/?tag=releasenotes%23keywords%23javascript

If you are upgrading from 1.x to 2.0 of the SDK, please see the upgrading notes for information on how to migrate existing code to work with the new major version.

Installing

In the Browser

To use the SDK in the browser, simply add the following script tag to your HTML pages:

<script src="https://sdk.amazonaws.com/js/aws-sdk-2.700.0.min.js"></script>

You can also build a custom browser SDK with your specified set of AWS services. This can allow you to reduce the SDK’s size, specify different API versions of services, or use AWS services that don’t currently support CORS if you are working in an environment that does not enforce CORS. To get started:

http://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/building-sdk-for-browsers.html

The AWS SDK is also compatible with browserify.

For browser-based web, mobile and hybrid apps, you can use AWS Amplify Library which extends the AWS SDK and provides an easier and declarative interface.

In Node.js

The preferred way to install the AWS SDK for Node.js is to use the npm package manager for Node.js. Simply type the following into a terminal window:

npm install aws-sdk

In React Native

To use the SDK in a react native project, first install the SDK using npm:

npm install aws-sdk

Then within your application, you can reference the react native compatible version of the SDK with the following:

var AWS = require('aws-sdk/dist/aws-sdk-react-native');

Alternatively, you can use AWS Amplify Library which extends AWS SDK and provides React Native UI components and CLI support to work with AWS services.

Using Bower

You can also use Bower to install the SDK by typing the following into a terminal window:

bower install aws-sdk-js

Usage and Getting Started

You can find a getting started guide at:

http://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide

API reference at:

https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/

Usage with TypeScript

The AWS SDK for JavaScript bundles TypeScript definition files for use in TypeScript projects and to support tools that can read .d.ts files. Our goal is to keep these TypeScript definition files updated with each release for any public api.

Pre-requisites

Before you can begin using these TypeScript definitions with your project, you need to make sure your project meets a few of these requirements:

Use TypeScript v2.x
Includes the TypeScript definitions for node. You can use npm to install this by typing the following into a terminal window:
```
npm install --save-dev @types/node
```
If you are targeting at es5 or older ECMA standards, your tsconfig.json has to include 'es5' and 'es2015.promise' under compilerOptions.lib. See tsconfig.json for an example.

In the Browser

To use the TypeScript definition files with the global AWS object in a front-end project, add the following line to the top of your JavaScript file:

/// <reference types="aws-sdk" />

This will provide support for the global AWS object.

In Node.js

To use the TypeScript definition files within a Node.js project, simply import aws-sdk as you normally would.

In a TypeScript file:

// import entire SDK
import AWS from 'aws-sdk';
// import AWS object without services
import AWS from 'aws-sdk/global';
// import individual service
import S3 from 'aws-sdk/clients/s3';

NOTE: You need to add "esModuleInterop": true to compilerOptions of your tsconfig.json. If not possible, use like import * as AWS from 'aws-sdk'.

In a JavaScript file:

// import entire SDK
var AWS = require('aws-sdk');
// import AWS object without services
var AWS = require('aws-sdk/global');
// import individual service
var S3 = require('aws-sdk/clients/s3');

With React

To create React applications with AWS SDK, you can use AWS Amplify Library which provides React components and CLI support to work with AWS services.

With Angular

Due to the SDK’s reliance on node.js typings, you may encounter compilation issues when using the typings provided by the SDK in an Angular project created using the Angular CLI.

To resolve these issues, either add "types": ["node"] to the project’s tsconfig.app.json file, or remove the "types" field entirely.

AWS Amplify Library provides Angular components and CLI support to work with AWS services.

Known Limitations

There are a few known limitations with the bundled TypeScript definitions at this time:

Service client typings reflect the latest apiVersion, regardless of which apiVersion is specified when creating a client.
Service-bound parameters use the any type.

Why use Node.js for Web Development? Benefits and Examples of Apps

Front-end web development has been overwhelmed by JavaScript highlights for quite a long time. Google, Facebook, Wikipedia, and most of all online pages use JS for customer side activities. As of late, it additionally made a shift to cross-platform mobile development as a main technology in React Native, Nativescript, Apache Cordova, and other crossover devices.

Throughout the most recent couple of years, Node.js moved to backend development as well. Designers need to utilize a similar tech stack for the whole web project without learning another language for server-side development. Node.js is a device that adjusts JS usefulness and syntax to the backend.

What is Node.js?

Node.js isn’t a language, or library, or system. It’s a runtime situation: commonly JavaScript needs a program to work, however Node.js makes appropriate settings for JS to run outside of the program. It’s based on a JavaScript V8 motor that can run in Chrome, different programs, or independently.

The extent of V8 is to change JS program situated code into machine code — so JS turns into a broadly useful language and can be perceived by servers. This is one of the advantages of utilizing Node.js in web application development: it expands the usefulness of JavaScript, permitting designers to coordinate the language with APIs, different languages, and outside libraries.

What Are the Advantages of Node.js Web Application Development?

Of late, organizations have been effectively changing from their backend tech stacks to Node.js. LinkedIn picked Node.js over Ruby on Rails since it took care of expanding responsibility better and decreased the quantity of servers by multiple times. PayPal and Netflix did something comparative, just they had a goal to change their design to microservices. We should investigate the motivations to pick Node.JS for web application development and when we are planning to hire node js developers.

Amazing Tech Stack for Web Development

The principal thing that makes Node.js a go-to environment for web development is its JavaScript legacy. It’s the most well known language right now with a great many free devices and a functioning local area. Node.js, because of its association with JS, immediately rose in ubiquity — presently it has in excess of 368 million downloads and a great many free tools in the bundle module.

Alongside prevalence, Node.js additionally acquired the fundamental JS benefits:

quick execution and information preparing;
exceptionally reusable code;
the code is not difficult to learn, compose, read, and keep up;
tremendous asset library, a huge number of free aides, and a functioning local area.

In addition, it’s a piece of a well known MEAN tech stack (the blend of MongoDB, Express.js, Angular, and Node.js — four tools that handle all vital parts of web application development).

Designers Can Utilize JavaScript for the Whole Undertaking

This is perhaps the most clear advantage of Node.js web application development. JavaScript is an unquestionable requirement for web development. Regardless of whether you construct a multi-page or single-page application, you need to know JS well. On the off chance that you are now OK with JavaScript, learning Node.js won’t be an issue. Grammar, fundamental usefulness, primary standards — every one of these things are comparable.

In the event that you have JS designers in your group, it will be simpler for them to learn JS-based Node than a totally new dialect. What’s more, the front-end and back-end codebase will be basically the same, simple to peruse, and keep up — in light of the fact that they are both JS-based.

A Quick Environment for Microservice Development

There’s another motivation behind why Node.js got famous so rapidly. The environment suits well the idea of microservice development (spilling stone monument usefulness into handfuls or many more modest administrations).

Microservices need to speak with one another rapidly — and Node.js is probably the quickest device in information handling. Among the fundamental Node.js benefits for programming development are its non-obstructing algorithms.

Node.js measures a few demands all at once without trusting that the first will be concluded. Many microservices can send messages to one another, and they will be gotten and addressed all the while.

Versatile Web Application Development

Node.js was worked in view of adaptability — its name really says it. The environment permits numerous hubs to run all the while and speak with one another. Here’s the reason Node.js adaptability is better than other web backend development arrangements.

Node.js has a module that is liable for load adjusting for each running CPU center. This is one of numerous Node.js module benefits: you can run various hubs all at once, and the environment will naturally adjust the responsibility.

Node.js permits even apportioning: you can part your application into various situations. You show various forms of the application to different clients, in light of their age, interests, area, language, and so on. This builds personalization and diminishes responsibility. Hub accomplishes this with kid measures — tasks that rapidly speak with one another and share a similar root.

What’s more, Node’s non-hindering solicitation handling framework adds to fast, letting applications measure a great many solicitations.

Control Stream Highlights

Numerous designers consider nonconcurrent to be one of the two impediments and benefits of Node.js web application development. In Node, at whatever point the capacity is executed, the code consequently sends a callback. As the quantity of capacities develops, so does the number of callbacks — and you end up in a circumstance known as the callback damnation.

In any case, Node.js offers an exit plan. You can utilize systems that will plan capacities and sort through callbacks. Systems will associate comparable capacities consequently — so you can track down an essential component via search or in an envelope. At that point, there’s no compelling reason to look through callbacks.

Final Words

So, these are some of the top benefits of Nodejs in web application development. This is how Nodejs is contributing a lot to the field of web application development.

I hope now you are totally aware of the whole process of how Nodejs is really important for your web project. If you are looking to hire a node js development company in India then I would suggest that you take a little consultancy too whenever you call.

Good Luck!
